Specification of Letters Patent.

Patented June 318, 131%.

Application filed November 26,1915. Serial No. 83,396.

To all whom it may concern.

B'e'itknowntha/tLJosEPH J. ltinnr, a citizen oi" the' United States, residing at Toledo, in the county of Lucas and State oi Ohio, have invented certain new and useful Innprovements in Automatic Automobile-Prowith the necessity tectors; and I do=declarc thefollowing to be a full, clear, and-exact description of the-invention, such-as will enable others'skil'led in the art to which it appertains' to makeand uset-he same, reference'being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form-a part of this specification The loss and annoyance resulting from. the theft 0r unauthorized use of automobiles are well' understood and of frequent occur rence; My-invention is'designed to prevent thesetroublesby providinga device which will invariably. set off an alarin 'and at the same timerender the engine of the-machine inoperative when any attempt is'made to purloin-the car. More particularly, my invention is designed to furnish an electrical safety device which includes a permutation switch and in which the knowiedige of certain selected numbers-is necessary in order to permit the use-of the car,

for any key or lock or fastening device.-

To these ends my invention consists of the devices hereinafter described, and shown and illustrated-in the accompanying drawings, inwhich- Figure l-is a diagrammatic View of my safety device, andFig'. 2, a perspective view on an enlarged scale of the fuse piece hereinai'tsr referred'to:

In-the drawings; A represents a switch designed to beactnated by the opening of the 'hocd of-an automobile 1B- is-a switch to beoporated by throwing into service'the sparking device of the engine, and O is a switch which is intended to be closed by' turning on the gasole'ne'. These three switches are held'normally open'by suitable springsand are thrown, respactively into closed relation with their respective contactpoints as stated: Thesccontactpoints a 7 '-c are connected by line 1 with one'side' of battery 2. Theswitchesardconnected; respectively,- with line 3 leading w crmutation switchbeard fixed on ther das board of thecar. This permutationeswitchboand 'is thus dispensing:

the only exposed part of my device, the remainder being inclosed within the hood; The batteries herein referred to; may, however, be disposed under the seats or elsewhereas may be most'convenient, it'being understood, however, that they and their connections are inclosed and: inaccessible.

While I have shown three switches 'A-B and C in the'line 13 it will beunderstood, without illustration, that this line may include other switches, tion, by'themovement of the'brake-lever or the motor-lever or any other part the movement of which-is necessary in the operation of the car.

The permutation switchboardreferred to consists of a dial-plate or board through which protrudes aseries of'metal contactpoints arranged in a circle and plainly numbered for illustration, from one'to' twenty. The ries a flat'metal' ring 5 within and concentric with the circle of contact-points. Behind the board the contact-points are, by means ofwvires (3, all connected together electrically except that two selected contactpoints are 0mitted,-in the present instance the numbers five and twelve. The centrally pivotally mounted handsring 5 and their outer ends are-capable of being swung. into contact with either of the numbered points. Line 3 is connected with the ring 5.-

The'line 6 is connected by 1ine8 with a fuse 9. This fuse consists of two springarms, 10 and 11, connected and held under tension-by a'fuse-wire'12. From the springarm ll leads line 13 back to the battery 2. When" the spring-arm 11 is released it contncts'with point 14 from which leads line 15 to buzzer 16 which, in this instance, is anapparatus for'making, when ina closed circuit, a loud and unusual noise. From the buzzer 16 leads a line 17 to thebattery 2.

So long as the hands 7 are in contact with the neutral points 5 12 on the switchboard i'the switches AB and (3 may be opened and-closed at will without any electrical efiect, for the reason that the circuit is open between the ring 5 and the line'6; When the owner leaves his car with the gasolene turned on, the hood closed and the sparkingswitch turned out of service position, he moves one or both of the hands 7 into actuated, for illustraa inthe-present instance, board 4 also car-v 7 slide upon the the engine,

contact with other numbered contact-points on the board 4. Now if either of the switch ABC be disturbed by opening the hood or turning on the gasolene or moving the sparking switch, or by disturbing any other working part provided with a suitable switch in line 13, the circuit will be closed through line 1, appropriate switch AB or (/,'line 3, ring 5, hands 7, wire 6, wire 8, spring-arm 10, fuse-wire 12, spring-arm 11 and wire 13 back to battery 2. The closing of this circuit linstantly, burns ofi fuse-wire 12, permitting arm 11 to spring into contact with point 14, now

causing the current to flow from battery 2 through line 13, arm 11, point 14, line 15, buzzer 16 and line 17 back to the battery. The closing of this latter circuit causes the noise making device 16 to operate, the noise continuing until the circuit is broken. The mere restoring of the hands 7 to the neutral points on the board 4 will not stop the noise as the noise-box is now in a circuit which excludes the switchboard.

18 is a switch-point with which the springarm 10 contacts when released by the burning of the fuse-wire 12. From the point 18 leads wire 19 which is connected with wire 20 leading from the sparking switch 21 through the sparking-coil-box 22 to the spark-plug 23 on the engine 24:. Sparking switch 21 is connected through line 25 with one side of battery 26 the other side of which is grounded through line 26 on the engine. The sparking switch 21 is also connected with one side of magneto 27 by line 28 the other side of the magneto being groundedthrough line 27 upon the engine.

At the instant that the fuse-Wire 12 is burned the sparking circuit either from the battery 26 or the magneto 27 is short circuited, cutting out the sparking coil 22 and the sparking plug 23. If the battery 26 be connected with the sparking circuit then the short circuit will be through line 25, switch 21, line 20, line 19, spring arm l0 and line 8-8 to ground on the engine, the other side of the battery 26 being also grounded on the engine through line 26. If the magneto be switched into the sparking circuit then the burning of the fuse will short cir= cuit through line 28, switch 21, lines 20 and 19, spring-arm 10 and line 88 to ground on the magneto being also grounded upon the engine through the line 27 It will now be seen that when an unauthorized use of the car is attempted, after the hands 7 have been set against such use, an alarm will be sounded and the sparking mechanism. will at once be rendered inoperative. Upon the return of the owner to his car, assuming that it has not been disturbed, it is only necessary for him to restore the. hands to the neutral numbers, known only to himself and to other proper persons, to

'ing device and 'for starting avoid the sounding of the alarm or the short circuiting of thesparking devices.

To those skilled in the art of constructing and wiring electrical apparatuses many alterations widely difiering from this illustrative embodiment of my invention will suggest themselves. Therefore these disclosures are notintended to be in any sense limiting.
